Carry out the following checkings:
1) Outside temperatures must be included between 10°C and 43°C.
2) Turn on the appliance and wait 30 minutes before the use if the external temperature is "low".
3) Check power input.
4) Carry out at least one full quick cooling cycle
Should the appliance have been transported horizontally instead of a vertical position DO NOT START THE

ALARMS AND SIGNALS (TAB.5)

DESCRIPTION OF ALARMS AND SIGNALS

EFFECT
In STOP blocks the start of blast chill.
In blast chill causes the blockage of the
cycle and the card returns to STOP.
In conservation, the cycle is not
blocked and the compressor is
activated cyclically (see parameters
C5, C6 and C7).
In defrost it is signalled with no effect
on adjustment
In STOP, in blast chill and in
conservation has no effect.
An eventual defrost terminates for
timeout.
In STOP not considered.
In blast chill not considered
In conservation it is considered but with
no effect on adjustment
In STOP not considered.
In blast chill not considered
In conservation it is considered but with
no effect on adjustment
In STOP not considered.
In blast chill the ventilator and
compressor outlets are kept
deactivated until the cause that
generated it does not pass (the buzzer
does not sound).
In conservation not considered.
The machine does not operate as there is
no electrical power.

TESTING

RE-SET
Check the connections and the operation
of the chamber probe
Check the connections and the operation
of the evaporator probe
The alarm is automatically recalled if the
cause that generated it remains unknown
The alarm is automatically recalled if the
cause that generated it remains unknown
The alarm is automatically recalled if the
chamber temperature falls below the
value of A8 -2° C
If the machine was in conservation it
continues to chill: the alarm is recorded
only if the temperature in the chamber
is above the setpoint r2 + A2.
If the machine was in STOP it returns to
that state.
If the machine was in blast chill the
cycle re-starts from the beginning.
